This issue is more likely to affect devices that use virtual machine tools and nested virtualization features, such as CloudPC, DevBox, Azure Virtual Desktop. We are investigating to determine the exact conditions under which this issue may be triggered. Windows Home Edition users are less likely to experience this issue as virtualization is less prevalent in private environments.
While our investigation is ongoing, this update is not being offered through Windows Update and Windows Update for Business. For this reason, this update may not be offered for your device at this time.
Microsoft is actively working on resolving the issue and plans to include the fix in an upcoming update.
